Would the release of sperm have an effect on my testicles 17 days after testicular torsion surgery?

Swelling/numbness/pain after torsion surgery are common after this type of surgery. Ice and antiinflammatories can help. Intercourse/masturbation should be OK after 14 days, but avoid squeezing the scrotum or other things that cause increased pressure until it fully healed. Watch for any redness/discharge at the incision site.

No. But pl hold sex/ masturbation till you heal. Good luck
